DIAL FOR THE TRANSFER IMPLEMENTS IN MACHINES FOR KNITTING WELT ED ANDOTHER FABRICS.

2 Application filed May 1'2, 1925. Serial No. 29,761.

To all whom it may concern:

Be it known that I, JEAN BAr'ris'rn V100, citizen of the FrenchRepublic, residing at Colombes, Department of Seine, France, haveinvented certain new and useful Improvements in Dials for the Transfer1m.- plements in Machines for Knitting lVelted and Other Fabrics, ofwhich the following is a specification.

My present invention has for its object an improvement in theconstruction of the dials provided with transfer implements, intendedfor the production of double inturns or welts of stockings and for thelongitudinal mock seam of stockings. These dials are usually made of asingle piece, comprising a central part, provided with narrow radialslots in which are guided the tails of the dial ii'nplements, and aperipheral part, provided with vertical radial fins consisting of thinplates fitted and secured, usually by soldering, in radial grooves ofsaid peripheral part; between which radial peripheral fins of the dial.slide the spaced outer portions of the dial implements.

This method of manufacture results in weakening the periphery of thedial, which is liable to give way and to produce, on the lower face ofthe dial, projections upon which the yarn may be caught, thus causingdefects in the fabric and in the longitudinal mock-seam of the stockingand also,

in many cases, breakage of the cylinder needles.

According to my invention, the dial is made of two disc members, adaptedto fit into one another and the outer of the said disc members isprovided, at its periphery, with radial vertical fins, integral with themember. The inner disc member, accurately fitted in the. outer one, andsecured to the same, is provided with radial grooves designed to guidethe tails of the dial implements.

This new method of manufacture allows of obtaining dials of very greatstrength, adapted to be made entirely by machinework and alwaysremaining free, upon their lower face, from any projections liable tocatch the yarn of the knitted web so that the lower face of theperipheral part of the dial always remains perfectly that, in case ofinjury, which is, not likely,

smootln Moreover, 1t 1s a considerable advantage of one of the discmembers of which the dial is composed, the damaged disc member can bereadily changed without requiring the replacen'ient of the other discmember.

My invention is hereinafter fully described, reference being had to theannexed drawing, in which:

Fig. 1 is a perspective view of a part of the inner member of the dial.

Fig. 2 is a perspective view of a part of the outer member of the dial.

Fig. 3 is a plan view of a part of the dial, with the outer and innermembers thereof fitted together.

Fig. 4,- is a vertical axial section of a part of the dial, with theouter and inner members thereof fitted together.

As shown, the dial consists of two disc members fitting into oneanother, the larger disc having no recess or notch upon its lower face;and these discs consist of the following: I

1. An outer disc 6, having, at its periphery, grooves 6 which aresufiiciently wide to allow the spaced outer portions 0 of the dialimplements a to slide therein. These grooves a leave between them thinwalls or fine 0 which form an integral part of the disc 0, which istherefore in no way weakened but remains rigid and free fromdistort-ion;

2. A central or inner disc f, fitting accurately into the first disc andprovidedwith radial grooves 7 designed to guide the tail of the dialimplements 0.

These two discs 6 and f are secured together by any suitable means,preferably by rivets e engaged in registering holes in the disc members(Figs. 3 and 4t).

hat I claim is A A dial for transfer implements for knitting machinesfor knittmg welted and other fabrics, the dial con'iprising, twoseparate disc members fittable one into the other, there being an outerand an inner one, integral radial vertical fins projecting from theupper face and at the periphery of the outer disc member, radial groovesprovided in the upper face of the inner disc member, and means forsecuring the disc members together, for the purpose described. I

In testimony whereof I have signedmy name to this specification.
